Happy 23rd Birthday Taylor Swift!

Taylor Swift turns 23 today (December 13)! A few days ago she Tweeted: “December 13th is my 23rd birthday, and also the premiere of my 23rd video. How fun.”

The I Knew You Were Trouble singer explained three years ago why she loves the number 13.

“The significance of the number 13 on my hand … I paint this on my hand before every show because 13 is my lucky number — for a lot of reasons. It’s really weird.”

She further explained, “I was born on the 13th. I turned 13 on Friday the 13th. My first album went gold in 13 weeks. My first #1 song had a 13-second intro,” she said. “Every time I’ve won an award I’ve been seated in either the 13th seat, the 13th row, the 13th section or row M, which is the 13th letter. Basically whenever a 13 comes up in my life, it’s a good thing.”
